[0034] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present application.

[0035] It should be understood that although terms such as first and second may be used herein to describe various components, these components should not be limited by these terms. These terms are used to distinguish one component from another. Therefore, the first component discussed below may be referred to as the second component without departing from the teachings of the concept of the present application. As used herein, the term "and / or" includes any one of the associated listed items and all combinations of one or more of them.

[0036] Those skilled in the art can understand that the accompanying drawings are only schematic diagrams of exemplary embodiments and may not be to scale. The modules or processes in the accompanying drawings are not necessarily essential for implementing the present application and thus cannot be used to limit the protection scope of the present application.

[0037] Currently, two different sealing methods are adopted for the charging socket to ensure the sealing between the front housing and the terminal and between the rear housing and the terminal. An O-ring is used to seal between the front housing and the terminal, while a combination of a gasket and a tail cover is used to seal between the rear housing and the terminal.

[0038] The function of the gasket is to integrally enclose various structures inside the front housing and the rear housing. At the same time, a plurality of through holes are provided on the gasket for wires to pass through. This design enables the charging socket to maintain overall sealing during installation and use. However, due to the existence of the through holes, if the sealing effect at any one of the through holes deteriorates, the sealing of the terminal will decrease. Therefore, the sealing effect of the terminal of the charging socket lacks stability.

[0039] In view of this, the embodiments of the present application provide a sealing structure to solve at least part of the above technical problems by separately sealing the terminal 300.

[0040] Please refer to Figure 1 , Figure 1The structural explosion diagram of a sealing structure provided by an embodiment of the present application. The sealing structure includes a first housing 100, a second housing 200, a terminal 300, and a seal 400. The first housing 100 includes a first body 110, and the first body 110 has a first mounting groove 111. The second housing 200 includes a second body 210, and the second body 210 has a second mounting groove 211; the first housing 100 is connected to the second housing 200, and the second mounting groove 211 communicates with the first mounting groove 111 to form a receiving cavity 500. The first body 110 and the second body 210 are in a sealed connection (any means capable of realizing the seal between the first body 110 and the second body 210 can be used, and the seal between the first body 110 and the second body 210 is not limited in this embodiment), that is, the connection between the first body 110 and the second body 210 is a sealed connection. Therefore, for the terminal 300, it is also necessary to seal between the terminal 300 and the first body 110, and to seal between the terminal 300 and the second body 210. Please refer to Figure 13 , Figure 13 The sectional structure diagram of the sealing structure of an embodiment of the present application. The terminal 300 is disposed in the receiving cavity 500. The terminal 300 includes a first connecting portion 310 and a second connecting portion 320. The first connecting portion 310 is connected to the second connecting portion 320. The first connecting portion 310 is disposed in the first mounting groove 111, and the gap between the first connecting portion 310 and the first mounting groove 111 is a first gap 140. The second connecting portion 320 is disposed in the second mounting groove 211, and the gap between the second connecting portion 320 and the second mounting groove 211 is a second gap 230. The seal 400 is disposed in the first gap 140 and abuts against the terminal 300 and the first body 110 respectively; and the seal 400 is disposed in the second gap 230 and abuts against the terminal 300 and the second body 210 respectively. The function of the seal 400 is to prevent external substances from entering the receiving cavity 500 and ensure good sealing at the connection between the terminal 300 and the first housing 100, and at the connection between the terminal 300 and the second housing 200.

[0041] Among them, both the first connecting portion 310 and the second connecting portion 320 are annular. Regarding the thicknesses of the first connecting portion 310 and the second connecting portion 320, the thickness range of the first connecting portion 310 satisfies 0.8 mm to 1.5 mm, and the thickness range of the second connecting portion 320 satisfies 0.8 mm to 1.5 mm.

[0042] Regarding the inner and outer diameters of the first connecting portion 310 and the inner and outer diameters of the second connecting portion 320, the following situations exist:

[0043] Situation 1, the outer diameter of the first connecting portion 310 is the same as the outer diameter of the second connecting portion 320, and the inner diameter of the first connecting portion 310 and the inner diameter of the second connecting portion 320 are not specifically limited and can be the same or different;

[0044] In the second case, the outer diameter of the first connecting portion 310 is different from the outer diameter of the second connecting portion 320; the difference between the outer diameter of the first connecting portion 310 and the outer diameter of the second connecting portion 320 is 0.1 - 0.7 mm, that is, the outer diameter of the first connecting portion 310 is 0.1 - 0.7 mm larger than the outer diameter of the second connecting portion 320 or the outer diameter of the second connecting portion 320 is 0.1 - 0.7 mm larger than the outer diameter of the first connecting portion 310; the inner diameter of the first connecting portion 310 and the inner diameter of the second connecting portion 320 are not specifically limited and can be the same or different.

[0045] In view of this, since the connection between the first body 110 and the second body 210 is a sealed connection, for the terminal 300, sealing between the terminal 300 and the first body 110 and sealing between the terminal 300 and the second body 210 can achieve the sealing of the terminal 300. In this embodiment, by separately sealing the terminal 300, the problem of poor stability of the sealing effect of the terminal 300 is solved; at the same time, in this application, the terminal 300 connected with the seal 400 can be installed in the accommodation cavity 500 to achieve the sealing of the terminal 300, and the assembly process is simple; in addition, this application does not require a relatively large gasket for sealing, reducing the materials of the sealing structure.

[0046] In some embodiments, please refer to Figure 2 , Figure 2 which is the overall structure diagram of the first stop component in the embodiment of this application. The first housing 100 further includes a first stop component 120, and the first stop component 120 surrounds the first installation groove 111 and is connected to the first body 110. Please refer to Figure 3 , Figure 3 which is the overall structure diagram of the second stop component in the embodiment of this application. The second housing 200 further includes a second stop component 220, and the second stop component 220 surrounds the second installation groove 211 and is connected to the second body 210. Please refer to Figure 4 , Figure 4 which is the overall structure diagram of the terminal at an angle in the embodiment of this application. The terminal 300 further includes a first installation portion 330, and the first connecting portion 310 is connected to the second connecting portion 320 through the first installation portion 330; one side of the first installation portion 330 close to the first connecting portion 310 abuts against the first stop component 120, and one side of the first installation portion 330 close to the second connecting portion 320 abuts against the second stop component 220.

[0047] Among them, the first mounting portion 330 is annular, the thickness range of the first mounting portion 330 is 0.8 mm to 1.5 mm, and the outer diameter of the first mounting portion 330 is smaller than the diameter of the first mounting groove 111. The outer diameter of the first mounting portion 330 can be the same as the outer diameter of the first connecting portion 310 and different from the outer diameter of the second connecting portion 320; or, the outer diameter of the first mounting portion 330 can be the same as the outer diameter of the second connecting portion 320 and different from the outer diameter of the first connecting portion 310; or, the outer diameters of the first mounting portion 330, the first connecting portion 310, and the second connecting portion 320 are all the same; or, the outer diameter of the first mounting portion 330 is smaller than the outer diameter of the first connecting portion 310 and smaller than the outer diameter of the second connecting portion 320; or, the outer diameter of the first mounting portion 330 is larger than the outer diameter of the first connecting portion 310 and larger than the outer diameter of the second connecting portion 320. That is to say, this embodiment has flexibility and diversity in actual production.

[0048] In view of this, in this embodiment, the relative position of the terminal 300 in the accommodation cavity 500 is defined by the abutment of the first stopping component 120 and the first mounting portion 330, and the abutment of the second stopping component 220 and the first mounting portion 330. The presence of the first stopping component 120 and the second stopping component 220 can enhance the stability and reliability of the connection and prevent the movement of the terminal 300. In addition, the connection method of the first mounting portion 330 and its contact with the first stopping component 120 and the second stopping component 220 further consolidate the stability of the sealing structure and ensure the reliable connection of the terminal 300.

[0049] In some embodiments, the terminal 300 further includes a first transition portion 340. The first transition portion 340 is provided on one side of the first mounting portion 330 close to the first connecting portion 310 to connect the first mounting portion 330 and the first connecting portion 310; the first transition portion 340 has a calibration hole 341. The portion of the first transition portion 340 surrounding the first mounting portion 330 serves to connect the first mounting portion 330 and the first connecting portion 310.

[0050] Among them, when the outer diameter of the first connecting portion 310 is the same as the outer diameter of the first mounting portion 330, the first connecting portion 310 is connected to the first mounting portion 330 through the first transition portion 340; the first transition portion 340 can be arc-shaped or plate-shaped or a plurality of spaced arc-shaped structures or a plurality of spaced plate-shaped structures, etc. The first transition portion 340 can also not be provided, and the first connecting portion 310 is directly connected to the first mounting portion 330; the connection surface between the first connecting portion 310 and the first mounting portion 330 is a part of the first mounting portion 330 on the side close to the first connecting portion 310.

[0051] When the outer diameter of the first connecting portion 310 is different from the outer diameter of the first mounting portion 330, the first transition portion 340 includes a first bending portion 342 and a second bending portion 343. The first bending portion 342 is arc-shaped, and the second bending portion 343 is arc-shaped. When the outer diameter of the first connecting portion 310 is smaller than the outer diameter of the first mounting portion 330, the first bending portion 342 extends obliquely from the side of the first mounting portion 330 close to the first connecting portion 310 towards the first connecting portion 310, and the second bending portion 343 extends obliquely from the side of the first bending portion 342 away from the first mounting portion 330 towards the first connecting portion 310 and is connected to the first connecting portion 310. When the outer diameter of the first connecting portion 310 is larger than the outer diameter of the first mounting portion 330, the second bending portion 343 extends obliquely from the side of the first connecting portion 310 close to the first mounting portion 330 towards the first mounting portion 330, and the first bending portion 341 extends obliquely from the side of the second bending portion 343 away from the first connecting portion 310 towards the first mounting portion 330 and is connected to the first mounting portion 330.

[0052] In view of this, in this embodiment, a suitable connection method is selected according to the size relationship between the outer diameter of the first connecting portion 310 and the outer diameter of the first mounting portion 330. Therefore, the applicable range of this embodiment is wide and the structural combination methods are diverse.

[0053] In some embodiments, the first stop component 120 surrounds the first mounting groove 111 and is connected to the first body 110. The first stop component 120 has at least one stop groove 150, and the notch of the stop groove 150 faces away from the first body 110.

[0054] In some embodiments, when there are two stop grooves 150, please refer to Figure 5 , Figure 5 which is an overall structure diagram of the first stop component of the embodiment of the present application. The two stop grooves 150 divide the first stop component 120 into a first stop portion 121 and a second stop portion 123. The first stop portion 121 surrounds the first mounting groove 111 and is connected to the first body 110. The side of the first stop portion 121 away from the first body 110 abuts against the first transition portion 340. The second stop portion 123 surrounds the first mounting groove 111 and is connected to the first body 110. The side of the second stop portion 123 away from the first body 110 abuts against the first mounting portion 330. The first stop component 120 includes a first protrusion 122, and the first protrusion 122 is provided on the side of the first stop portion 121 close to the first mounting groove 111. The first protrusion 122 can be clamped in the calibration hole 341.

[0055] Among them, the side of the first stop portion 121 close to the first mounting groove 111 is in contact with the first transition portion 340. The side of the second stop portion 123 close to the first mounting groove 111 abuts against the side of the first mounting portion 330 close to the first connecting portion 310.

[0056] In view of this, in this embodiment, the position of the terminal 300 in the accommodation cavity 500 is defined by the first protrusion 122 and the calibration hole 341. One side of the first stop portion 121 close to the first installation groove 111 is in contact with the first transition portion 340, and the extended portion on the second stop portion 123 abuts against one side of the first installation portion 330 close to the first connection portion 310, increasing the connection strength between the first stop assembly 120 and the terminal 300.

[0057] In some embodiments, please refer to Figure 6 , Figure 6 which is an overall structural diagram of the terminal from another angle in the embodiment of the present application. The terminal 300 further includes at least one first extension portion 350. The first extension portion 350 is provided on one side of the first installation portion 330 close to the first connection portion 310 and is connected to the first installation portion 330. There is a gap between one side of the first extension portion 350 away from the first installation portion 330 and the first connection portion 310.

[0058] In view of this, the first extension portion 350 in this embodiment increases the total area of the periphery of the first installation portion 330 (the first installation portion 330 also needs to be connected to other structures, so the larger the total peripheral area, the more conducive to the connection between the first installation portion 330 and other structures; the other structures are not specifically defined here). The gap between the first extension portion 350 and the first connection portion 310 reserves a position for installing the seal 400.

[0059] In some embodiments, as Figure 4 and Figure 6 shown. There are two first extension portions 350. The first transition portion 340 and the two first extension portions 350 divide the end face of one side of the first installation portion 330 close to the first connection portion 310 into a first stop surface 331, a second stop surface 332, a third stop surface 333, and a fourth stop surface 334. The first stop surface 331 is within the calibration hole 341, the second stop surface 332 is between the first transition portion 340 and one first extension portion 350, the third stop surface 333 is between the two first extension portions 350, and the fourth stop surface 334 is between the first transition portion 340 and the other first extension portion 350.

[0060] In some embodiments, when there are four stop grooves 150, please refer to Figure 7 , Figure 7Another overall structure diagram of the first stop component according to an embodiment of the present application. Four stop slots 150 divide the first stop component 120 into a third stop portion 124, a fourth stop portion 126, a fifth stop portion 128, and a sixth stop portion 129. The third stop portion 124 surrounds the first mounting slot 111 and is connected to the first body 110. One side of the third stop portion 124 away from the first body 110 abuts against the first transition portion 340. The fourth stop portion 126 surrounds the first mounting slot 111 and is connected to the first body 110. One side of the fourth stop portion 126 close to the first mounting slot 111 contacts the first transition portion 340. The fifth stop portion 128 surrounds the first mounting slot 111 and is connected to the first body 110. One side of the fifth stop portion 128 away from the first body 110 abuts against the first mounting portion 330. The sixth stop portion 129 surrounds a part of the first mounting slot 111 and is connected to the first body 110. One side of the sixth stop portion 129 close to the first mounting slot 111 contacts the first transition portion 340.

[0061] The first stop component 120 includes a third protrusion 125, a fourth protrusion 127, and a fifth protrusion 130. The third protrusion 125 is provided on one side of the third stop portion 124 close to the first mounting slot 111. The third protrusion 125 can be clamped in the calibration hole 341, and the third protrusion 125 abuts against the first transition portion 340. The fourth protrusion 127 is provided on one side of the fourth stop portion 126 close to the first mounting slot 111. The fourth stop portion 126 abuts against the first mounting portion 330. The fifth protrusion 130 is provided on one side of the sixth stop portion 129 close to the first mounting slot 111. The sixth stop portion 129 abuts against the first mounting portion 330.

[0062] Among them, please refer to Figure 8 , Figure 9 and Figure 10 , Figure 8 is a state diagram when the terminal of the embodiment of the present application is connected to the first housing, Figure 9 is a detailed view of the connection between the terminal and the first housing of the embodiment of the present application, Figure 10Schematic diagram of the connection relationship between the terminal and the first stop component according to an embodiment of the present application. When the terminal 300 is installed in the first installation groove 111, the terminal 300 is connected to the first stop component 120. Specifically, the third protrusion 125 can be engaged in the calibration hole 341, the third protrusion 125 abuts against the first stop surface 331, and the side of the third stop portion 124 close to the first installation groove 111 contacts the periphery of the first transition portion 340. The fourth protrusion 127 is at one end of the fourth stop portion 126 away from the third stop portion 124. The fourth protrusion 127 is between the first transition portion 340 and a first extension portion 350, and the fourth stop portion 126 abuts against the second stop surface 332. At the same time, a part of the side of the fourth stop portion 126 close to the first installation groove 111 contacts the first transition portion 340. The fifth stop portion 128 is between the two first extension portions 350. The fifth protrusion 130 is at one end of the sixth stop portion 129 away from the third stop portion 124.

[0066] When the outer diameter of the second connecting portion 320 is different from the outer diameter of the first mounting portion 330, the second transition portion 370 includes a third bending portion 371 and a fourth bending portion 372. The third bending portion 371 is arc-shaped, and the fourth bending portion 372 is arc-shaped. When the outer diameter of the second connecting portion 320 is smaller than the outer diameter of the first mounting portion 330, the third bending portion 371 extends obliquely from the side of the first mounting portion 330 close to the second connecting portion 320 towards the second connecting portion 320, and the fourth bending portion 372 extends obliquely from the side of the third bending portion 371 away from the first mounting portion 330 towards the second connecting portion 320 and is connected to the second connecting portion 320. When the outer diameter of the second connecting portion 320 is larger than the outer diameter of the first mounting portion 330, the fourth bending portion 372 extends obliquely from the side of the second connecting portion 320 close to the first mounting portion 330 towards the first mounting portion 330, and the first bending portion 341 extends obliquely from the side of the fourth bending portion 372 away from the second connecting portion 320 towards the first mounting portion 330 and is connected to the first mounting portion 330.

[0067] In view of this, in this embodiment, a suitable connection method is selected according to the size relationship between the outer diameter of the second connecting portion 320 and the outer diameter of the first mounting portion 330. Therefore, the applicable range of this embodiment is wide and the structural combination methods are diverse.

[0068] In some embodiments, please refer to Figure 11 , Figure 11 which is the overall structure diagram of the second stop component of the embodiment of the present application. The second stop component 220 has a fifth stop surface 221. The fifth stop surface 221 is the side of the second stop component 220 facing the second mounting groove 211, and the fifth stop surface 221 is in contact with the periphery of the second transition portion 370. As Figure 9 shown, the end surface of the second extension portion 360 away from the first mounting portion 330 is a sixth stop surface 361, and the sixth stop surface 361 abuts against the second body 210.

[0069] In view of this, in this embodiment, the second stop component 220 abuts against the first mounting portion 330, and the fifth stop surface 221 on the second stop component 220 is in contact with the periphery of the second transition portion 370 and cooperates with the sixth stop surface 361 to abut against the second body 210.
